Reaccion psicofisiológica a la exposición de imágenes de mujeres delgadas en universitarias Rosa Margarita Zuvirie Hernández María Dolores Rodríguez Ortiz Multidisciplinaria (Ciencias Naturales y Exactas) delgadez pensamientos Imagen corporal evaluación psicofisiológica Los estándares sociales del modelo de belleza prodelgadez, está llevando a que algunas mujeres jóvenes se preocupen, especialmente aquellas más susceptibles a estos modelos. A partir de esto la internalización del ideal de delgadez representa un factor de riesgo en el desarrollo de la preocupación por la imagen corporal. Por ello, fue importante realizar un estudio que contemplara el tipo de pensamientos hacia la imagen corporal y la reacción psicofisiológica ante imágenes de mujeres delgadas. Para tal efecto se realizó una evaluación psicofisiológica a 40 mujeres de 19 a 25 años estudiantes de Licenciatura. La muestra se dividió en dos grupos: el grupo con pensamientos negativos hacia la imagen corporal y el grupo con pensamientos positivos. Se utilizó un diseño exploratorio. Los resultados del estudio indican que no hay diferencias estadísticamente significativas en la reacción psicofisiológica ante imágenes de mujeres delgadas en el grupo con pensamientos positivos y negativos hacia la imagen corporal. Dichos resultados señalan que la exposición a estas imágenes no provoca variaciones en la reacción psicofisiológica de las mujeres, probablemente debido a que ellas no tienen insatisfacción corporal significativa, lo que muestra que es necesario emplear mejores métodos para evaluar la imagen corporal. 2011 artículo científico 2007-1523 https://www.redalyc.org/articulo.oa?id=425741615004 es http://www.redalyc.org/revista.oa?id=4257 Revista Mexicana de Trastornos Alimentarios application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Trastornos Alimentarios (México) Num.1 Vol.2
